Execution monitoring method for e.g. digital transmission content protection protocol, involves verifying instructions in case of reception of abort indication of process, where instructions are implemented by CPU for execution of protocol
Execution monitoring method for e.g. digital transmission content protection protocol, involves verifying instructions in case of reception of abort indication of process, where instructions are implemented by CPU for execution of protocol
The method involves receiving an input message from a communication network (220) using a reception unit, where the message is processed by a CPU (203) of a receiver device (200) or an audio-video source device along a communication protocol and marks the beginning of a process. A set of instructions is verified using an integrity verification unit in a case of reception of abort indication of the process by the CPU using a checksum controller (230), where the set of instructions is implemented by the CPU for the execution of the communication protocol. Independent claims are also included for the following: (1) a computer program product comprising a set of instructions for performing an execution monitoring method (2) a computer readable storage medium comprising a set of instructions for performing an execution monitoring method (3) a device comprising a CPU and an interface module.
